Citric acid – Austria
Citric acid is used in cosmetics as a so-called buffering agent, i.e. it adjusts and stabilizes the product’s pH value. The pH of healthy skin is between 3.8 and 4.8, and in terms of its well-being, it is important to support this balance with products that have a pH value that close to the skin’s natural pH. In addition, the preservatives in cosmetic products require a suitable pH to be maintained. Citric acid is produced by biofermentation.
